Bad service

Friday my wife saw the kids soccer boots at woodmead Nike factory on 60% off sale. Then on Saturday we had to drive from Winchester hills (JHb south) to woodmead, we had to queue to enter the Nike outlets premises. Got the soccer boots and some other Nike stuff, when I was with the cashier, I’m about to pay for my sons soccer boots whom I’ve already sent him a picture of what I’m buying him . The boom those soccer boots are both right sided, the cashier went to the store room and back to the shelves to check the left sided boot and after some time she told me that they can’t find any and there’s nothing they can do. Had to go back to the shelves to choose the other soccer boots which are now bit more expensive from what I chose before. No one apologised for the inconvenience cost, I even asked them to give me the replacement soccer boots on that 60% off which made me drive from my house to woodmead but my proposal was declined. I think my consumer rights were violated. I’m still furious I even asked them if they are doing this because it’s an outlet or what. Now we had to pay more for black colour, our initial choice was grey and orange. Had to bring home a black soccer boots. My son is not impress at all. Such an inconvenience hey
